The Institute of Electrical and Electronics Engineers (IEEE), IEEE Computer Society. Approved 21 September 2000. 29 р. This recommended practice addresses the architectural description of software-intensive systems. A software-intensive system is any system where software contributes essential influences to the design, construction, deployment, and evolution of the system as a whole.
The purpose of this recommended practice is to facilitate the expression and communication of architectures and thereby lay a foundation for quality and cost gains through standardization of elements and practices for architectural description.
